In the current work, new cobalt incorporated fluorapatite encapsulated iron oxide nanocatalyst (γ-Fe₂O₃@FAp@Co) was prepared and characterized by using FT-IR, XRD, SEM, TEM, VSM, and EDX techniques. The catalyst was utilized in the synthesis of novel derivatives of symmetric bis-triazoles by the reaction of various aldehydes and butane-1,4-diyl bis(hydrazinecarbimidothioate) in ethanol at room temperature. γ-Fe₂O₃@FAp@Co was easily removed from the reaction mixture using an external magnet and was used several times without decreased catalytic properties. This method provided a novel approach for the green synthesis of bis-triazoles in excellent yield (88–95%) and reasonable reaction time (60–80 min). The structures of prepared compounds were confirmed by analytical methods.

在目前的工作中，使用 FT-IR、XRD、SEM、TEM、VSM 和 EDX 技术制备并表征了新的掺钴氟磷灰石包封的氧化铁纳米催化剂（γ-Fe ₂ O ₃ @FAp@Co）。该催化剂用于在室温下通过各种醛和丁烷-1,4-二基双（肼碳亚氨基硫酸酯）在乙醇中的反应合成对称双三唑的新型衍生物。γ-Fe ₂ O ₃@FAp@Co 很容易使用外部磁铁从反应混合物中去除，并且可以多次使用而不会降低催化性能。该方法为以优异的收率（88-95%）和合理的反应时间（60-80 分钟）绿色合成双三唑提供了一种新方法。制备的化合物的结构通过分析方法得到证实。
